Study And Design Of Erosion Control Structures For Ndoro, Ikwuano L.G.A. Abia State
Abstract
The study and design of Erosion
control structures for Ndoro. lkwuano L.G.A. Abia State was carefully carried
out the parameters needed for the design were well defined b identifying the
major causes of gully erosion in the site as a result of poor sanitation of'
the community. People using the already existing erosion control structures as
a refuse dump site which over time had blocked the channel part, creating a
parallel channel instead of the installed channel, thereby causing the gully
formation. The lined trapezoidal channel were designed carrying 2.4m7s. the
slope calculated as 1.4%. velocity of flow 3.58rn/s while the catchment area
was estimated as 25 hectares. A roughness coefficient of 0.015 was used, while
runoff coefficient of 0.48 were selected. a trapezoidal channel of bottom width
0.82m. depth of flow 0.49m. and top width 2.78m were designed respectively to
control the erosion by conveying the runoff to Aqua-Ibo River which serve as
the outlet discharge point using this type of channel, the runoff will be
safely discharged and the gully site totally reclaimed.
